The WaveBlaster is a personal watercraft (PWC) made by Yamaha Motor Corporation. Part of their WaveRunner line of watercraft, the Yamaha WaveBlaster 700 (Marine Jet 700TZ) made its debut in 1993. As a one-person personal water craft with a motorcycle-like ride that let riders enjoy sharply banked turns, tailstands, combined with its powerful engine, semi flat-bottomed hull, and chrome-alloy piston rings, this is a model that still has many devoted fans today.

1987-1991 The precursor to these machines was the Yamaha WaveJammer, produced from 1987-1991. It was the world’s first sit-down type solo riding personal water craft. The combination of a fixed steering column and small hull made this a particularly agile model. It featured a 500cc twin cylinder engine, with a top speed around 25-30 mph on a smooth lake. The engine can be replaced with the newer 701cc engine, with minimal fitting problems.
1993 through 1994 The craft remained unchanged with the 61X cases and blue/purple color paint commonly referred to as "blurple".
1995 Yamaha changed the color to red.
1996 Yamaha added dual 38mm Mikuni carburetors and 62T cases to the WaveBlaster, resulting in slightly more power, from 63 to 73 hp. This model was discontinued in 1996.
1997 through 1998 Yamaha changed the color scheme to blue and white and renamed the machine to WaveBlaster Limited (not available in USA).
This ski came from the factory as a stripped down no-frills machine, it does not have a tachometer, speedometer, GPS, rear view mirrors, cup holder, ice box, luggage compartment or a reverse mechanism that are typical of larger multi-person skis. Yamaha also manufactured a WaveBlaster 2 and a WaveBlaster 3, the latter more commonly known as the WB800 in reference to its 800cc motor.
The WaveBlaster has been described by many as "the closest thing to riding a motorcycle on water".
